Networking for Project and Thesis

TCP/IP provides end to end data transmission between devices along with some other functionalities like addressing, mapping and acknowledgement. TCP/IP is a combination of two protocols. TCP controls the messages by dividing them into packets. IP controls the transmission of these packets from sender to the receiver.

TCP/IP protocol layers

Following are the four layers of TCP/IP:

Application layer

Transport layer

Internet layer

Physical layer

Working of TCP/IP protocol

Client/Server model is used as a mode of communication by TCP/IP. It works in the following way:

Application layer consists of various applications for data exchange with use of protocols like HTTP(Hypertext Transfer Protocol), FTP(File Transfer Protocol), SMTP(Simple Mail Transfer Protocol)

Transport layer provides end-to-end communication between the host and the user. It uses protocol UDP(User Datagram Protocol).

Internet layer is responsible for transfer of packets over the network and uses IP(Internet Protocol) for this purpose.

Physical layer provides interconnection between the nodes.

Advantages of TCP/IP protocol

It can be easily modified.

It is compatible with all the operating systems.

It is scalable in determining the most appropriate path.

Thus it is a good topic for M.Tech thesis as well as for research. A student can get thesis help on this topic from experts specialized in thesis guidance. You can also explore the internet for further details on this topic.

NS2

Another good computer networking topic for an M.Tech thesis is NS2. NS stands for Network Simulator. It is an open-source, discrete-event based network simulator mainly used for research purpose and for teaching. It provides help in simulating routing protocols like IP, TCP, UDP etc. It creates a simulation environment for studying the network. Following steps are followed while creating a simulation environment:

Topology Definition

Development of the model

Configuration of the link

Execution

Analysis of the problem

Visualization

NS2 create network topologies and then examines the behavior of the network under any event. The behavior is analyzed by tracing down the events. NS2 provides text-based as well as animation-based simulations.

Advantages of NS2

It has the ability to support multiple protocols.

It can represent network traffic graphically.

It can also support multiple algorithms for routing and queuing.

NS2 is a very good topic for an M.Tech thesis in computer networking field. You will not only get theoretical knowledge but also practical experience of network simulator tool. You can get thesis help about NS2 from an expert who has practical knowledge about how to use this tool.

MANET

MANET stands for mobile ad hoc Network and is another good choice for an M.Tech thesis topic in networking. In MANET, the nodes are self-configurable and have the ability to move freely in any direction and can link with other devices frequently. MANET was originally used as military project in defense. MANET have the challenges of weak signal strength, reliability, power consumption along with some other problems.

Characteristics of MANET

Each node is independent in nature i.e. each node act as the host as well as the router.

It is based on distributed nature of operation for security and configuration.

The network is dynamic in nature I.e each node can join and exit the network at any time.

The nodes in the network are associated with less memory and power.

In MANET, the bandwidth remains fluctuating.

MANET creates a symmetric environment such that all the nodes have identical features like responsibilities and capabilities.

Hurdles in the path of MANET

There are certain hurdles in the path of MANET, which it has to overcome. Some of these are:

The reliability of the transmission is affected by certain factors like data loss, interference, and blockage.

The rate of transmission is limited to a certain range thus there is reduced data rate.

Packet loss can occur while transmission of data.

Frequent path breaks.

Lack of firewall results in security issues in the network.

This was just the introduction to MANET to give an overview of what it is if you are going with this topic for your M.Tech thesis.

Network Security

Network Security is the set of rules to ensure the safety of the network of an organization or personal network. You can choose this topic for your M.Tech thesis if you have complete understanding of how the data is transferred over the network. Network Security also include security of physical hardware devices. Network Security in software means providing authorized access to the network by means of ids and passwords.

Whenever a user tries to access the network, his authenticity is checked by means of ids and passwords. This is done to prevent any malicious user entering the network by the motive of hacking it.

Types of attacks to network

Active Attack – In this type of attack, a hacker tries to make changes to data while it is being sent from one node to another.

Passive Attack – In this type of attack, an outsider monitors system of the organization consistently to find vulnerable ports.

Network Security Tools

Following are some of the tools employed in network security:

Wireshark

Aircrack

Snort

BackTrack

Netcat

Thus if you really have significant knowledge(practical + theoretical) of networking tools, security

measures then you should choose this topic for M.Tech thesis. Besides, you will get thesis help on this topic from computer networking experts.
